Collection: High Potassium Fertilizers
Potassium is critical for plant vigor and is an essential macronutrient in plants (the K in N-P-K). Potassium, or Potash, exists in most types of organic matter and primarily provides a good ionic environment for plant metabolic processes to happen. Plants that are deficient are more susceptible to diseases and frost damage. Potassium plays a key roll in strengthening cell walls, therefore decreasing a cell’s permeability and susceptibility to damage. Too much potassium can lead to a high pH. Wood ash is often suggested as a source of potassium, but we do not recommend its use as it is very difficult to know just how much potassium is in the ash and you can unknowingly impact your soil pH. Find out what your soil's needs are by ordering a soil analysis test kit.
